To all whom it may concern:

Be it known that I, WILLIAM KLocKn, a citizen of the United States,residing in the borough of Brooklyn, county of Kings, city and State ofNew York, have invented certain new and useful Improvements in Presses,of which the following is a specification.

This invention aims to provide an improved press for bending metal andespecially for the bending of long articles, such for example as theparts of automobile or other vehicle frames.

The accompanying drawings illustrate an embodiment of the invention.

Figure 1 is a front elevation of the ma chine partly in section. Fig. 2is an end elevation thereof. Fig. 3 is a plan, partly in horizontalsection at different planes.

Referring to the embodiment of the invention illustrated, an upper fixeddie holder A and a lower movable die holder B are provided, dies ofsuitable shape being fastened thereon in accordance with the characterof the work.

The machine is provided with a number of posts C passing through lowercross supports D and through the base E which extends continuously fromend to end. The length of the machine is divided into a number of panelsor parts by the locating of the cross supports D and posts 0 atintervals.

Extending continuously along the machine at the top is the continuouscross beam F in the under side of which the upper die is carried, andwhich takes the reaction of the upper die continuously along its length,as the base E takes the reaction from the lower die.

The lower die carrier B is guided upon the several posts C by tubularguides Gr. Its movement is obtained by means of a series of togglemechanisms spaced at numerous short intervals along its length, so as tocommunicate a substantially uniform pressure along the length of thework, and to minimize bending strains upon the .die and carrier andimperfections in the Work. Preferably two such toggles are arranged ineach panel of the machine, the toggles along the entire length of theapparatus being equally spaced. The toggle links are H and J, the latterconstituting also an arm upon a shaft K having a similar arm L which isSpecification of Letters Patent.

oscillated by the toggle actuating link M. In each panel of the machinebetween the two toggles H and J an actuating arm L and link M arelocated, so as to give a balanced strain. The several actuating links Mare driven by means of cranks N on a shaft 0 running continuouslyalongside the frame of the machine inlaterally extending bearings P andactuated from a driving shaft Q at a slow speed through theintermediation of pinions and gears R S T U V and W, with a ratio forthe complete system of 120 to 1. The level of the floor from which thework is controlled is indicated at X.

An important feature of the invent-ion is the division of the toggleshaft K into short lengths as shown in Fig. 1, each equal to one of thepanels of the machine so that each unit or element of the apparatus canwork independently of the others. The twisting strains can be muchreduced and the apparatus can be arranged to operate upon work pieces ofvarious lengths.

A wedge is used for adjusting the fixed die A. The adjustment is madesubstantially uniform throughout the length of the die, without callingfor a wedge of too great thickness by dividing the face of the adjustingwedge Y into a series of short inclines Z engaging correspondinginclines upon the top of the die holder A, each of the inclines Z beingof suflicient length to take care of the amount of adjustment which willprobably be required, and the movement of the adjusting wedge beingeffected by means of adjusting bolts a I) carried in supports 0 (Z uponthe fixed cross beam F of the machine and engaging opposite ends of theadjusting wedge so as to shift the latter to the right or to the left asoccasion demands.

That I claim is 1. A press for shaping vehicle frames or the like,including in combination an elongated die, a plurality of separateshafts and a plurality of actuating devices engaging said shafts andengaging said die at a plu rality of points along its length.

2. A press for shaping vehicle frames or the like, including incombination an elongated die, and a plurality of separate shafts andtoggles between said shaft and said die and engaging said die at aplurality of points along its length.

3. A press for shaping vehicle frames or the like, including incombination, an elongated die, a plurality of shafts in fixed bearings,and means operated by each of said shafts for actuating said die.

4. A press for shaping vehicle frames or the like, including incombination an elongated die, a plurality of shafts in fixed bear ings,and a toggle between each of said shafts and a part of said die.

5. A press for shaping vehicle frames or the like, including incombination an elongated die, plurality of shafts in fixed bearings, atoggle between each of said shafts and a part of said die, and a commonshaft for actuating the several toggles simultaneously.

. 6. A press for shaping vehicle frames or the like, including incombination a pair of elongated carriers A and B, a plurality of togglesH and/J engaging the carrier B at a plurality of points along itslength, said toggles being arranged in pairs with the members J of eachpair constituting arms on a common shaft, and an operating arm L onsaidshaft between the members J of said pair.

7. A press for shaping vehicle frames or the like, including incombination a fixed die holder A, a movable die holder B, a shaft KWILLIAM KLOCKE.
